DWI | T1 and T2 | T1 with contrast | MRS-NAA level | MRS-lactate level | MRS-lipid level | MRS-choline level | |
---|---|---|---|---|---|---|---|
LDD | T2 shine through | hypointense on T1; hyper-intense on T2 | typically no enhancement | Decreased (−) | Increased (+) | no lipids | Decreased (−) |
Medullo-blastoma | restricted diffusion | isointense on T2 | enhancement | Decreased (− − −) | Increased (++) | lipids | Increased (+) |
